' SAFETY DEVICE FOR WATER-GAGES.

Application filed January 2 may concern:

Be it known that I, FRANK HENRY BAB- COCK, a citizen of the UnitedStates of America, residing at Pittsburgh, in the county of Alleghenyand State of Pennsylvania, have invented. certain new andiusefulImprovements in Safety Devices for Water- Gages, of which the followingis a specification, reference being had therein to the accompanyingdrawing.

This invention relates to a safety device for water gages, and theprimary object of m invention is the provision of positive and reliablemeans, in a manner as hereinafter set forth for housing a water gagewhereby it can be safely used, without any danger of persons 1n thevicinity of the gage being injured by water and pieces of glass when thegage bursts.

Another object of this invention is to furnish a water gage with a noveljacket or housing that is of such shape as to retard water and brokenpieces of glass when the gage bursts, the water and glass beingdeflected in a direction that prevents persons from being injured.

A further object of this invention is to furnish a water gage with anovel sectional jacket that has transparent plates in proximity to thegage whereby it can be easily observed. a

A still further object of this invention is to accomplish the aboveresults by a mechanical construction that will be here-. inafterspecifically described and then claimed.

Reference will now be had to the drawing, wherein Figure 1 is aperspective view of the safety device as applied to a gage, Fig. 2 is anenlarged vertical sectional view of the device, Fig. 3 is a frontelevation of the device, Fig. 1 is an elevation of the inner side 0 adetachable section of the device, and Fig. 5 is a horizontal sectionalview of the device.

Further describing my invention in detail with reference to the drawingwherein like numerals denote corresponding parts throughout: 1 denotes awater pipe provided with a gage holder 2 for a water gage 3 that hassuitable connections for the purposes for which it is employed.

1 denotes an oblong jacket that has top and bottom plates 5 and 6provided with bosses 7 to receive the gage 3 and one of Specification ofLetters Patent.

these bosses rests upon the holder 2 for supporting the jacket. Thebottom plate 6 has a drain nipple 8 upon which can be placed a drainpipe 9. The bottom and top plates 5 and 6 are pear-shaped or triangularin plan and the bosses 7 are located at the acute angles of said plateswhile the drain opening is approximately central of the bottom plate 6.

The jacket 4: has the front side thereof provided with an oblong opening10 and detachably mounted in said opening, be tween the top and bottomplates 5 and 6 is an angle plate 11 which is substantially V-shaped incross section. The angle plate 11 has side flanges 12 provided withnotches 13 and the sides of the jacket 1 are provided with lugs 14:having pockets 15. The angle plate 11 can be placed with the lugs 14fitting in the notches 13. By then lowering the angle plate the upperwalls 16 of the notches 13 can be seated in the pockets 15 whereby theangle plate will be detachably-held in engagement with the jacket. Theangle plate 11 is provided with seats 17 for inner beveled transparentplates 18, the seats 17 cooperating with the walls of the opening 10 inholding the inner transparent plates. The angle plate 11 hasoblongopenings 19 and holders 20 for outer transparent plates 21. Thetransparent plates 18 and 9.1 are disposed at an angle relatively to thegage 3 and on account of expansion and contraction the inner transparentplates 18 are held in position by resilient clips 22 that are secured inthe angle of the plate 11 by screws 23 or other fastening means. Theplates 18 and 21 permit of the gage 3 being easily observed and thelarge space within the jacket readily accommodates water and brokenglass until it can escape through the pipe 9 \Vith the walls of theangle plate 11 disposed at an angle relatively to the gage 3 brokenglass is deflected into the jacket and with the transparent plates ofsuitable thickness said plates are not injured by broken glass, andwater is confined within the jacket without any danger of a person beingscalded or injured.

It is thought that the utility of the safety device will be ap arentwithout further description and while in the drawing there isillustrated a preferred embodiment of the invention. it is to beunderstood that the structural elements are susceptible to such againstthe jacket 7 further provided at its front with variations andmodifications as fall within the scope of the appended claims.

What I claim is 1. A safety device for water gages comprising a jacketprovided with a drain and further provided at its front with an opening, a supporting plate extending into said opening and detachablyconnected to said jacket, said plate associated with said jacket toprovide an inner seat, a transparent plate mounted in said inner seat,said supporting plate provided with an outer seat, and an outertransparent plate mounted in said outer seat and arranged parallel toand spaced from said inner transparent plate.

2. A safety device for water gages comprising a jacket provided with adrain and an opening, a supporting plate extending into said opening anddetachably connected to said jacket, said plate associated with saidjacket to provide an inner seat, a transparent plate mounted in saidinner seat, said supporting plate provided with an outer seat, an outertransparent plate mounted in said outer seat and arranged parallel toand spaced from said inner transparent plate, and resilient meanscarried by said jacket and engaging said inner transparent plate forconstantly maintaining it against its seat.

3. A safety device for water gages comprising a jacket provided with adrain and having the forward portion thereof V- shaped in plan andthrough which is adapted to extend the gage glass, said forward portionof said jacket having an oblong opening, a supporting plate detachablyconnected to said forward portion and having a part thereof extendinginto said opening and associated with the walls of the opening Copies ofthis patent may be obtained for five cents to provide a pair of innerseats, inner transparent plates mounted in said inner seats, saidsupporting plate provided with means to provide a pair of outer seats,and outer transparent plates mounted in said outer seats and arrangedparallel to and spaced from said inner transparent plates, the seat partof said supporting plate and the said inner transparent platesfOIHllIlO' closures for said opening.

4. A safety device for water gages com prising a jacket provided with adrain and having the forward portion thereof V- shaned' in plan andthrough which is adapted to extend the gage glass, said forward portionof said jacket having an oblong opening, a supporting plate deta'cha-blyconnected to said forward portion and having a part thereof extendinginto said opening and associated with the walls of the opening toprovide a pair of inner seats, inner transparent plates mounted in saidinner seats, said supporting plate provided with means to rovide a pairof outer seats, outer transparent plates mounted in said outer seats andarranged parallel to and spaced from said inner transparent plates theseat part of said supporting plate and the said inner transparent platesforming closures for said opening, and means connected to said part ofsaid supporting plate and engaging the inner transparent plates formaintaining them against their seats.

In testimony whereof I afiix my signature in the presence of twowitnesses.
